The trial has started in Phoenix for two white supremacist brothers from Illinois charged in a 2004 bombing that injured a black city official in Scottsdale.

The federal trial of twin brothers Dennis and Daniel Mahon has
been extended several times since their 2009 arrest at their home
in Davis Junction, Ill., because of the extensive amount of
evidence.

They pleaded not guilty in the Feb. 26, 2004, bombing in which a
package detonated in the hands of Don Logan, Scottsdale's diversity
director at the time. It injured Logan's hand and arm and also hurt
a secretary.

Prosecutors and defense attorneys are expected pick jurors by
Wednesday and opening statements are scheduled for Thursday
morning.

he brothers are charged with conspiracy to damage buildings and
property by means of explosive.
